Application filed May 31, 1907, Serial n sves'zzl To. all whom Honey concern:

Be itknown that I, DAVIDIIB. WHITEHILL, a citizen-"of the United States,.residingat North Clarendon, inthe county of Warren and State of Pennsylvania, have, invented a new and useful Means for Cooling the Cylinders of Eimlosive-Engines, of which the following is aispecification. p The-presentinvention relates to mechanism forcirculating water or cooling medium through the jacket of an explosive engine, andthe principal object is. to provide a novel and simple circulating system whereby water may be conveyed from a tank or rcservolr to the cylinder otan explosive. en ine, said water being returned from the exp osive engine hack to the'reservoir or, tank, the latter eing located-so that the waterv contained therein isin nov danger of being frozen solid. The referred-embodiment of the -invention is ustrated insthe accompanying draw-- 'in s, wherein:

1 1 is a'view partly in elevation and 'art sectionof' the, novel nechanism. 2 is a detail sectional view, showing the v ve of the water supplyin means.

Similar'reference numeral drawings. 7 i v a In the embodiment disclosed, a tank or reservoir 3 is shown, which is located in the ground in convenient relation to the engine;-

I referably outside thebulldmg'containmgt e same; An explosive to be cooled, and

engine is shown-at i, said engine being of any suitable: type, and having a water jacketed cylinder 5; The engine shaft 6 is provided with an eccentric 7. Said eccentric ,has a link-connection 8 with one end of a walking beam 9. The other end of the walking beam is located over thetank or reservoir 3. This water circulating-system comprises a conduit leading from the, tank or reservoir 3 to the engine, and a rtugn conduit leading from the engine back to the .tank or reservoir, these conduits, in the preferred form of construction, being also connected to a common receptacle; As shown, the supply conduit consists of a plurality of sections, one 'of which is a pi e 10 suspended from the outer end of thewa king beam; The lower end of thepipe 10 is submer ed in the water of the tank-or reservoir, sai lower end carryin a valve casing 11, having an inlet 12 controlled by an inwardly opening valve '13. The upper end of the pipe hasa T-coupling 14,

. p I s designate-corresponding, parts in all-the figures .of the from which extends an offset pipe section 15, the dischargecnd of this pipe being. downturned in-the form of a'spout that is slidably engaged in the upper end of a stand pipe seqmunication with, the upper end of the barre-l or recep'thcle 18, and an overflow pipe section 21 also connected to the upper end of the barrel ,18 and having its outlet in the reser voir 3.'

During the operation of the engine, the walking beam 9 is rapidly operated, and therefore the supply conduit section 10 is rapidly reiprocated. As a result of. this rapid reciprocation, the water in the tank or reservoir'3 will beclevated-in said section 10, and will flow through the pipe section 15 into the stand pipe 16, and thence into the barrel or receptacle 18. In explanation of the elevating operation, it is to be noted that upon thedown stroke of the section 10', the same will move downwardlywith respect to the column of water contained therein because of the inertia of such column; Thus the valve-13 will be opened and admit water into the lower endof said section 10. The valve,

wardly into the upper portion of the receptacle, from which it returns'through the return ipe section 21', into the reservoir 3. It will thus .be evident that as 1011 as the engine is in operation, cold water wil be continuouslysuppiied to the cylinder, and the warmer. water returned to the reservoir,

where as it cools, it will sink, andthus be again taken. up, by the elevating mechanisam' By having the reservoir or. tank 3 in the ground, there is little liability of the watertherein freezing Winter, and at the same -time, such water will 'bemaintained in com paratively cool condition. 16 and receptacle lfi are believed to be advantageous inasmuch as a comparatively. large body of water is thusdis osed between.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention, will be apparent to those skilled in the art, without furtherdescription', and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may he resorted to without departing from the spirit or sacrificing any'of the advantages of the invention.

Having thus fully described my invention, whatl claim as new, and-desire to secure by Letters Patent, is:

.1. In mechanism of the class described, the combination with an explosive engine saving a water'jacketed cylinder, of a reservoir, a supply conduit connected to the water jacket of ,the engine and having an. inlet'section loosely suspended and operating in the reservoir, and means operated bythe beingsuspended from and supported by said actuating .means.

2, In mechanism of the class described, the combination with an open reservoir 10- ound, of an explosive engine having 'a water jacket and an engine shaft, a 'oonnection between the engine shaft and \inil} connected tothe water jacket and in cludin section suspended from the other lower end located and operating in the open eurried'by the lower end of the reciprocatory In mechanism of the character described, the combination with a reservoir located in the ground, of an explosive engine havinga'water jacket and an engine shaft, aconnection between the engine shaft and one end of the walking beam, a supply conduit connected to the water jacket and including a section loosely suspended from the other end of the-walking beam and having end submerged in the reservoir in lation tothe walls thereof, an in lvopeningyalve carried by the lower end of the pi e'section, and a return conduit 4. In mechanismof the character de- 5. In mechanism of the character described, the combination with a reservoir, of an explosive engine having a water acket, a supply conduit section connected to the engine and having an upstanding end portion,

a vertically movable supply conduit section having a valved lower end submerged in the reservoir, and having a downwardly turned upper end slidable in the upstanding end portion of the first mentioned section, and movable means from which the vertically moving section is suspended, said means being connected to and operated by the engine.

6. In mechanism of the class described,

the combination with a tank or reservoir located in the ground, of an explosive engine having a water jacket, a walkingbeam, a connection between one end of the walking beam and engine, a supply conduit connecting the tank or reservoir and the water jacket and comprising a vertically reciprocating elevating pipe section suspended from the other end of the walking beamand having its lower portion operating in the reservoir, an inwardly opening valve carried by the lower end of the pipe, a. receptacle having a lower. connection with the lower portion of the water jacket of the explosive engine, a stand pipesection connected to the lower portion of the receptacle, a conveyor section for conveying water from the upper portion of the suspended pipcsection to the upper portion of the stand pipe section, and a return conduit comprising sections connecting the upper portion'of the water jacket and the receptacle and the upper portion of the receptacle and the reservoir.

' in testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of twowitnesses.
